Someone from a family which has grown astronomically wealthy in the oil business, who has never had to work a tap in their life, and who may very well decide that they have nothing better to do with their free time than claim to be in touch with divinity, get a load of gullible people to follow them, and set about murdering innocent bystanders by the thousands. The two best known oil brats in the world at the time of writing reside (1) in the White House, and (2) probably somewhere in Afghanistan.

Advice on oil brats; don't vote for them, don't die for them, don't kill for them, certainly don't piss on them if they're on fire, leave them well enough alone.
